Blisters are a pretty common occurrence, especially for folks who are active or if their work requires them to be on their feet. Knowing the right first aid for blisters can help prevent infection and aids in helping blisters heal faster.
Blisters are a pocket or a bubble of fluid that’s found under the skin. Blisters happen when the skin gets inflamed or irritated, and the surrounding area sends fluid known as serum under the skin. It’s also possible for blood to pool under the blister instead, and when this happens it’s known as a blood blister. If there’s an infection, pus can also build up inside the blister.
This pocket of fluid acts as cushioning that protects the skin from further inflammation so long as it doesn’t get punctured. Blisters typically heal on their own in about a week.
However, blisters can also “pop” or leak on their own. When that happens, the blister can become prone to infection. It’s important to avoid popping the blister as much as possible, and if it does pop, be sure to keep the area sterilized to prevent infection.
Blisters usually develop on a person’s hands and feet. This is because these parts of the body are the ones usually exposed to irritation or inflammation. However, it’s also possible for blisters to develop on other parts of the body, depending on what the possible cause is.
Here are some of the possible causes of blisters:
Usually, the location or distribution provides a clue to the cause of the blister.
For the most part, blisters aren’t usually painful, and they can be a minor annoyance. However, some blisters, especially those that are infected, can cause a lot of pain, so it’s important to know what to do in case that happens.
Blisters usually get infected if they get popped. This is because bacteria can get under the skin of a popped blister and cause infection. This is why you should not pop your blister, and try to keep it intact as much as possible.
The only time it would be okay to pop a blister is if a doctor recommends it, and they will also be the one to do it.
If a blister gets infected, then the area under the skin can get filled with pus. This is a cloudy or opaque liquid that can be foul-smelling. The skin around an infected blister also feels warm, and it can be painful to the touch.
If left untreated, the infection could spread and cause more serious problems such as cellulitis or sepsis.
Blisters are usually a minor injury. But this doesn’t mean that you should neglect blisters, or you should not do any first aid when you have a blister.
Caring for blisters helps prevent infection, and also helps heal the blister faster. Here are some first aid tips as well as care tips for blisters:
